They breathe in air and exhale CO2 just like humans do.

Yes. You exhale carbon dioxide and oxygen. You breathe out normal air although the cabon dioxide level is greater and there is less oxygen.
Surprisingly, when animals exhale, they breathe out water, too! Much like plants take water and CO2 and turn it into foods, animals turn the food they eat back into water and CO2. In this way, plants and animals rely on each other. even more.
When you exhale you breath out.
Carbon dioxide is the waste substance that is exhaled when you breathe out. When you exhale, your body releases carbon dioxide that is produced during the process of converting the oxygen you breathe in into energy.
Atmospheric air has about 20.5% oxygen and our lungs only extract about 4.5% oxygen, so the air we exhale has about 16% oxygen, 4.5% CO2. The air we breathe into the victim then has 16% oxygen for their lungs to extract oxygen from.
